What Is the Rosemount 2088 Pressure Transmitter?
The Rosemount 2088 Pressure Transmitter is a versatile, high-accuracy device designed for gauge, absolute, and differential pressure measurement.
It measures process pressure and converts it into a reliable 4–20 mA or digital signal that can be monitored and controlled remotely. This makes it suitable for critical pressure, flow, and level measurement tasks in process control systems.
As part of the Rosemount Smart Transmitter Series, the 2088 combines proven sensor technology with smart diagnostics, ensuring long-term reliability, low maintenance, and superior process performance.
Working Principle of the Rosemount 2088
The Rosemount 2088 operates on the piezoresistive sensing principle — a reliable method for converting mechanical pressure into an electrical signal.
Here’s how it works:
-
The process pressure acts on an isolated sensing diaphragm within the transmitter.
-
This pressure is transmitted through a fill fluid to a piezoresistive sensor.
-
The sensor detects the change in resistance caused by diaphragm deflection.
-
The transmitter’s microprocessor converts this change into an electrical signal.
-
The resulting signal (analog or digital) represents the precise process pressure.
This design ensures fast response, excellent repeatability, and reliable long-term accuracy — even in changing process conditions.
